Frank Dillane is a British actor. He is the son of actors Stephen Dillane and Naomi Wirthner. His father is of English, Irish, Scottish, and remote Manx (Isle of Man), ancestry. Frank’s mother is evidently a black Jamaican woman. His uncle is actor Richard Dillane.

Frank’s paternal grandfather is John B. Dillane. John was born in Australia, and likely has Irish ancestry.

Frank’s paternal grandmother is Bridget M. Curwen (the daughter of Stanley Patricius Lamplugh Curwen and Lilian Frances Skinner). Bridget is English, and has English ancestry, with some remote Manx (Isle of Man) roots. Stanley was a Protestant minister, and was the son of Alfred Francis Curwen and Beatricia Cervinia Hills. Lilian was the daughter of Charles Lancelot Andrewes/Andrews Skinner and Lady Sara Kathleen Ponsonby.

There are claims on the internet that his father Stephen mentioned in a 2006 Australian interview that reggae changed his life and that he ended up marrying a Jamaican woman. I haven’t found the interview, though.
